Ultrasound operation
For optimal diffusion of the ultrasound and protection of the oscillating tank, nothing should be in
contact with the bottom of the bath during sonication. Laboratory
fl
asks and other sample vessels
must be stored in the supplied beaker holder or similar accessories. We recommend the use of
special holding clamps for
fi
xing the sample vessels in the holder (see Section 7). They prevent
the sample vessels from moving around or toppling over during sonication.
• It is possible to treat multiple sample vessels with different
fl
uids at the same time.
• When treating small quantities of combustible
fl
uids in sample vessels, the country-speci
fi
c
guidelines/ regulations that are currently in effect are to be observed!
The ultrasonic bath is turned off for inserting the beakers.
Insert the sample vessels into the beaker holder, ensuring:
•
The sample vessels must be immersed at least 2 cm deep in the contact
fl
uid.
•
Remove any air bubbles below the vessels.
• The
fi
ll level of the oscillating tank must always be at or slightly
above the
fi
lling level mark following equipment. A low
fi
ll level
will damage the ultrasonic bath!
Set the required sonication period and start the ultrasound, see
Section 3.1.1.
Following sonication, remove the sample vessels from the tank and set down atop a level
surface.
Caution:
Depending on the length of the sonication, the
fl
asks/samples may be hot.
Before the next sonication, verify the service life of the contact
fl
uid. Heed the speci
fi
cations
of the preparation manufacturer. If the solution in the ultrasonic bath becomes heavily
contaminated, it should be replaced earlier as it can reduce the ef
fi
cacy of the ultrasound.
Notes on the temperature of the bath
fl
uid:
• Ultrasound energy warms up the bath
fl
uid (even without additional heating). The temperature of
the bath
fl
uid can increase rapidly if the ultrasound is active for long periods of time and/or the
oscillating tank is covered.
• To protect the electronic components inside the ultrasonic bath, the ultrasound output is
reduced upon reaching a critical interior temperature in order to inhibit a further increase in the
temperature.
• The
fl
uid in the oscillating tank must not exceed a maximum operating temperature of 100°C.
